Subject:   PCMCIA modem problems

I am trying to get the port of the 2.0 pcmcia driver and daemon to 2.1 posted
by Dan Mutz <dmuntz@eecs.umich.edu> working.  The card I have is a Cardinal
28.8 modem.

Everything seems to be working find.  The kernel recognizes the insertion of
the card:

   Jan  5 14:51:47 kestrel /kernel: qcic: card inserted in slot 0

If pcmciad is running when the card is inserted, the whole system locks
up with the bell ringing until the card is removed.  It doen't work much
better if the card is inserted before pcmciad is started.

However, if the system is booted with the card in the slot things work a
lot better when pcmciad is started (see output below).  The daemon recognizes
the card and appears to configure the sio1 correctly:

        Jan  5 15:07:25 kestrel /kernel: sio1: type 16550A

But any attempt to open /dev/cuaa1 just hangs.

It would be perfectly acceptable to boot with the card in, so getting
around the hand is enough.

Bios is: PhoenixBIOS A486 1.03 04L

Any help greatly appreciated,
Mark <markd@grizzly.com>
